Milling machine

Chiron (Niemcy) Chiron Werke GmbH & Co. KG – Tuttlingen

The photo shows a Fanuc Series 0-M (a popular CNC controller used in the 1980s/90s).

It supports X, Y, Z axis interpolation and a tool magazine.

Features include a CRT screen and a classic push-button keyboard.

3. Electrical parameters (nameplate)

Power supply: 3-phase, 380 V, 50 Hz

Control voltage: (not specified, but typically Fanuc 110/220 V → transformer)

Auxiliary voltage: 24 V

Protection: 16 A (flink)

Electrical diagram number: 711 792 01 01

4. Machine construction

Vertical CNC machining center (milling machine) with a fully enclosed housing.

Worktable with grid of holes for mounting workpieces.

Carousel tool magazine (visible in the photo) – most often 12, 20, or 24 tools (depending on version).

Automatic tool changer (ATC).

Z-axis operates vertically (guideway assembly and telescopic way covers visible).

5. Typical technical data (for Chiron FZ 12/15 machines from this period)
